<p>PURPOSE:To obtain the photosensitive toner and electrophotographic sensitive body having a sufficient photosensitivity by essentially consisting a binder resin of a specific styrene/acrylic resin. CONSTITUTION:This toner contains the binder resin having an electrical insulating characteristic and zinc oxide and sensitizing dye as a photosensitive material. The binder resin consists essentially of the styrene/acrylic resin having <=9 acid value. The acid value is more particularly characteristic <=3. The acid value refers to the mg number of KOH required for neutralizing 1g styrene/ acrylic resin and is more particularly preferably a copolymer of styrene and methyl acrylate or methyl methacrylate.</p> |
